SPECIFICATION forming part of Letters Patent No. 781,525, dated January 31, 1905- applicati@ flied Meer 9,1904. serai No. 197,272.

.To all whom it may concern: l

Be it known that I, ARCHIBALD E. IsAAcs, a

citizen of the United States, and a resident of" the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Faucet, of which a simple, economic, and effective form of' fau-` l cet having' inlets for hot and cold water, fa

chamber in which the two may be mingled, and a single outlet.

The particular construction of the faucetre? lates to the expeditious and convenient manner in which through the manipu'lation of' a single handle the supply of hot or of cold water or the combined supply of both maybe turned on, regulated, and shut ofl'. v v

The invention 'consists in th e novel construeg tion and combination'of' the several parts, as will be hereinafter fully set forth', and pointed out in the claims.

Reference is to be had to the accompanyingV drawings, forming a part of' this specification, in which similarv characters of reference indi' cate corresponding parts in all the figures.

Figure 1 is a verticalsection through the faucet, showing both the cold and the hot wa* ter ports open. Fig. 2 is a vertical section taken practicallyvat right angles to the section shown in Fig. 1` on the line 2 2 of' Fig. 1. Fig. 3 is a horizontal section taken practically on the lines 3 3 of' Fig. 2. n Fig. 4 is a vertical central section through the improved faucet' constructed to rest upon a washstand or other support, the piston being inposition to`cut off the supply and the handle being in a position at a right angle to that illustrated' in Fig. 2 and the section being taken on practically the same line as Fig. 2. Fig. 5 is a section through the form of the device shown inFig. 4, and Fig. 6 isa detail view illustrating the location of the stop for the handle.

A representsthe body or casing of the faucet, in which the form shown in Figs. 1, 2, and 3 is provided with a chamber 10, which extends throughthe bottom of the said body or casing and is normally closed by a bottom plug 11. This chamber 10 is provided with a reduced branch 12 at its upper portion, and abovethe said branch 12 of the chamber an exterior'ly-threaded collar 13 is constructed,

-faround which a correspondingly-apertured .nut 14is screwed, a suitable packing intervening between the said collar and the said nut. In the extension or reduced portion 12 vlof the chamber 10 an aperture is made in ton and against the plug 11, fitting, preferably, in a recess in thelatter. The piston-.head lis provided with a central boss 18, having a washer 19 at its top, of' rubber or other suitable yielding material, and a stem 20 is passed through the'said boss and into the chamber 16`of the piston B, and where the stem 20 passes through the said boss the stern is polygonal in cross-section, and that portion of the stem which extends into the chamber 16 ofl the piston B is threaded to receive a suit- 'able nut 21, which acts to hold the stem firmly connected with the said piston and the washer 19 in position. y

A collar 22 is screwed upon the upper portion of' the body or casing A, and this collar is provided with a central opening which receives the lower end of" a cap C, which cap has a flange 23 at its bottom portion, and this. flange is fitted in a suitable recess in the top of the Abodyof the casing A and is beneath the .upper portion of the collar' 22, and the said cap C'is adapted to f'eeely turn in the bearings thus provided for it.

Near the upper portion of the stem a longitudinal slot .24 is produced, in the lower portion of' which a friction-roller 25 is located, 95

IOO

handle extends out through the opposite side of the cap C, a slot 27 being provided for such purpose, and in a wall of this slot 2T teeth 28 are produced adapted to receivea projection 29 from the handle, (shown in dotted lines in Fig.' 2,) and the remaining portion ofthe handle which extends beyond the cap is so .formed as to be conveniently grasped. rlhus by moving the handle up and down the piston B is moved in a corresponding direction, and by moving the handle laterally the cap C may be turned in its bearings, carrying with it the stem 2O and the piston B.

A channel 30 is produced in the casing A, leading into the chamber 10, which channel is adapted to be connected with asource of coldwatersupply, and in the same horizontal plane a second channel 31 is produced in the said casing, likewise leading into the chamber 10, and this latter channel 31 is adapted to be connected in any suitable or approved manner with a source of hot-water supply. On the upper portion or head of the piston B a fiange 32 is formed, extending slightly7 less than half the circumference of the said head, as is shown vin Fig. 3. so that when the. plunger is pushed down and turned in one direction the coldwater channel 30 is opened and the hot-water channel 31 is closed, as is shown in Fig. 3, and by turning the said piston slightly in another direction the two channels 30 and 31 are both opened and hot and cold water will flow into the chamber 10 and out through the nozzle 15. If hot water alone is required, the plunger is turned farther, so as to cover the port or channel 30 and leave the port or channel 31 open. Both these ports or channels 30 and 31 are closed in the normal position of the piston, the piston being held up by the spring 17, when the walls of thepiston will close the said ports or openings 30 and 31 in a perfectly tight manner, and the washer 19 at the upper portion of the piston will lit tightly against the upper wall of the chamber 10, below the extension 12 thereof, and thus effectually prevent any water from entering the nozzle 15. The spring 17 in the chamber 10 is forced downward and placed under additional tension when the handle 26 is carried downward, thus uncovering the aforesaid ports or channels 30 and 31, and either one or the other, or both, of the said ports or channels 30 and 31 are opened or closed more or less, according to the amount of depression of the handle 26 and according to the direction in which the handle 26 is laterally carried.

When the piston Bis forced downward, it is held in its lower position by reason of the projection 29 on the handle engaging with one or the other of the teeth 28, and these teeth are in plurality, and by carrying the piston B downward to a greater orlesser extent more or less of the openings or ports will be uncovered in a vertical direction. Vhen the piston is rotated, one or the other, or both, openingswill be more or less opened in a horizontal direction, and the piston may be held in its vertical and rotary adjusted position.

In Fig. 4 I have illustrated the same construction as that which is shown in Figs. 1, 2, and 3, with the exception that the plug 11 is dispensed with and the casing A is provided with a bottom surface adapted to rest upon or be'secured to any support. The channels a() and 31 are to turn down at right angles from their openings into the chamber 10 and run vertically through the substance of the casing A to be connected below to the hot and cold water pipes, respectively, in the usual approved manner. The casing A in this coustruction is made in two sections f/ and u', adjusted closely together by an inside flange on the upper part of the portion r/ lifting into an outside flange on the lower part of the portion a and held securel y together by a collar a2, screwed upon the upper part of the section a and with its iange catching and forcing down the section (n by engaging the collar on its outer circumference.

The object in separating the casing A into two portions t and a', as shown in 1 `ig. L1, is to permit of its being taken apart to insert the piston B or to remove it for renewing the washer or for other purposes. In the device as shown in Figs. 1 and 2 such insertion and removal are done by removal of the plug' 11. In the said Fig. A the piston B is shown in its upper position cutting off all supply of hot and cold water to the interior of the faucet.

One of the main points of the invention is to provide a construction which will absolutely prevent leakage from the faucet. 'lhis is accomplished by inoviding` in addition to the closely-fitting ground surface the central boss 18, having a washer 19 at its top, made of rubber or other suitable yielding material, which effectual] y closes ofi' the outlet simultaneously with its being closed by the upper motion of the piston. The washer 19 being of a more or less elastic material and held in place by a spring-pressure against the outlet elfcctually prevents any leakage that might possibly take place by escaping at the outlet or through the packing where the piston part enters the chamber should such packing become defective by use, as it generally does. Any desired provision may be made for the easy renewal of this portion if worn out by service.

It will be observed that the chamber in which the washer and the boss carrying it have movement is a l'nixing-chamber, as both cold and hot water passing through the inletports 3() and 31 enter the said chamber, where the water is thoroughly mixed and passes in its mixed condition to the outlet-nozzle.

Having thus described my invention, l claim as new and desire to secure by Letters Patenti- IOO ISO

, the piston, and locking devices closing both of said ports, a spring exerting outward tension on the piston, a segmental cut-0E llange carried by the piston, capable, as the piston is moved inward and revolved,

of-openingeither. one of said ports and clos-- ing the other, or of opening both ports` means for imparting rotary and end .movement to for the said means.

2. In a faucet, a casingprovidedwith a mixing-chamber having'a reduced upper section and opposing inlets leading into the main section of said chamber near the top, a nozzle connected with the reduced section of the mixing-chamber, a piston mounted Jr'or vertical and rotary movement in the main section of the mixing-chamber and provided with an upper extension member, a cushion on the said extension member, adapted to normally close eommunleatlon between the two sections of the mixing-chamber, a spring exerting up-l ward tensionfon 'the piston, a segmental cut` off flange at the upper portion of the piston,

vcapable when the piston is depressed of closing one and opening theother of the inlets, and means externally operated for imparting axial and rotary movement to the piston.

In testimony whereofIhave signed my name to this specification in the presence of two subscribing witnesses. y
